Pseudo-Ranks: The Better Way of Ranking? [PDF]
The American Statistician, 2021 Rank-based methods are frequently used in the life sciences, and in the empirical sciences in general.

Inference for rank-rank regressions
, 2023 The slope coefficient in a rank-rank regression is a popular measure of intergenerational mobility. In this article, we first show that commonly used inference methods for this slope parameter are invalid. Second, when the underlying distribution is not continuous, the OLS estimator and its asymptotic distribution may be highly sensitive to how ties in

A note on the gap between rank and border rank [PDF]
, 2017 We study the tensor rank of the tensor corresponding to the algebra of n-variate complex polynomials modulo the dth power of each variable. As a result we find a sequence of tensors with a large gap between rank and border rank, and thus a counterexample

Proceedings of the Twenty-Fifth International Joint Conference on Artificial Intelligence, 2016 We need to reason about rankings of objects in a wide variety of domains including information retrieval, sports tournaments, bibliometrics, and statistics. We propose a global constraint therefore for modeling rankings. One important application for rankings is in reasoning about the correlation or uncorrelation between sequences.

The Journal of Symbolic Logic, 2022 AbstractBuilding on Pierre Simon’s notion of distality, we introduce distality rank as a property of first-order theories and give examples for each rankmsuch that$1\leq m \leq \omega $. For NIP theories, we show that distality rank is invariant under base change.

Ranks and symmetric ranks of cubic surfaces [PDF]
Journal of Symbolic Computation, 2020 We study cubic surfaces as symmetric tensors of format $4 \times 4 \times 4$. We consider the non-symmetric tensor rank and the symmetric Waring rank of cubic surfaces, and show that the two notions coincide over the complex numbers. The corresponding algebraic problem concerns border ranks. We show that the non-symmetric border rank coincides with the

Ranking structures and rank–rank correlations of countries: The FIFA and UEFA cases [PDF]
International Journal of Modern Physics C, 2014 Ranking of agents competing with each other in complex systems may lead to paradoxes according to the pre-chosen different measures. A discussion is presented on such rank–rank, similar or not, correlations based on the case of European countries ranked by UEFA and FIFA from different soccer competitions.

Construction of a Uniform Access Structure Using Minimum Independent Dominating Vertices [PDF]
Engineering and Technology Journal, 2014 The most important technologies in modern society are the information security; it is founded to provide a protection to the transmitted data. Secret sharing scheme is one of the methods designated to protect the secret data. It is a method that allows a

Journal of Water and Climate Change, 2021 It is well recognised that the performance of climate model simulations and bias correction methods is region specific, and, therefore, careful validation should always be performed.
